Patients' characteristics and 30-day mortality for those undergoing elective surgeries during the COVID-19 pandemic in Bangladesh.

BACKGROUND: The COVID-19 pandemic has significantly impacted the surgical practice throughout the world, including elective surgical care. This study investigated the characteristics of patients undergoing elective surgery, the prevalence of COVID-19 infection, the surgical procedures performed, and 30-day mortality in general and pediatric surgical settings in selected tertiary-level hospitals in Bangladesh from November 2020 to August 2021. METHODS: This serial cross-sectional study included 264 patients scheduled for elective surgeries during the study period. All patients underwent COVID-19 real-time polymerase chain reaction (RT-PCR) testing within 24 hours before surgery. Data on age, sex, common comorbidities, surgical procedures, and 30-day mortality were collected and analyzed. Furthermore, comparisons were made between COVID-19 positive and negative patients. RESULTS: The prevalence of COVID-19 infection among patients was 10.6%. Older age, a history of major surgery within the last three months, hypertension, and diabetes mellitus were significantly associated with COVID-19 infection. All COVID-19-negative patients underwent surgery, while only 46.4% of COVID-19-positive patients underwent surgery. The most common surgical procedures were related to the digestive system, breast, and urinary system. Only one patient (0.4%) died within 30 days after surgery among the COVID-19-negative patients, whereas two patients (7.1%) died among the COVID-19-positive patients: one before surgery and one after surgery. CONCLUSIONS: This study provides valuable insights into the characteristics, burden of COVID-19 infection, and 30-day mortality of patients undergoing elective surgery in tertiary care centers in Bangladesh during the pandemic.

Miltefosine Induced Reduced Male Fertility Capacity after Treatment of Post Kala-azar Dermal Leishmaniasis, Bangladesh.

Post Kala-azar Dermal Leishmaniasis (PKDL) is the sequel of visceral leishmaniasis in Indian subcontinent and may appear among patients with or without previous history of visceral leishmaniasis (VL). The aim of the study is to understand the male reproductive safety profile of miltefosine used for the treatment of Post Kala-azar Dermal Leishmaniasis (PKDL) in Bangladesh. From January 2017 to March 2017, an exploratory study was carried out on male fertility capacity in Bangladesh among male patients above 14 years old with PKDL treated with miltefosine. Twenty nine male patients were included to observe the effect of miltefosine on reproductive health. All PKDL patients had history of visceral leishmaniasis (VL) in different time periods. Among them three (10.3%) patients were unable to ejaculate semen. In semen analysis, 3 patients (10.3%) were found azoospermia (sperm count & motility- 0, viscosity- good, pH- 7 to 8), microscopically there was presence of RBC (5-15/HPF), WBC (8-15/HPF). Another 3 patients (10.3%) were found oligospermia (sperm count- 4.2 to 15.3 million/ml, motility- 20 to 50%, viscosity- good, pH- 6 to 9, RBC- 4 to 15/HPF, WBC- 4 to 15/HPF). The study documented some important findings in evaluating male infertility and selection of drug regimens in treating PKDL patients with miltefosine for 12 weeks.

Evaluation of Post Guillain-Barre Syndrome (GBS) Patients: A Cross Sectional Study.

Guillain-Barre syndrome (GBS) is related with significant morbidity and also mortality. Little is known about the long term outcome of GBS patients who survived. The objective of this study is to determine the lasting outcome and consequences of GBS patients. This is a cross-sectional study of patients who diagnosed GBS and managed at the Intensive Care Unit of Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh from January 2004 to December 2017. All survived patients were invited for a structured interview, questionnaires, and full neurologic exam to record their current clinical condition focused on complaints and symptoms, neurological deficits, disabilities, behaviour, and quality of life. Thirty-eight patients participated, with a median age of 20 years (range 4-39 years) and a median interviewed time of 7 years (range 1-13 years). Residual complaints were reported by 24(63%) patients, including paresthesias (10.5%), unsteadiness of gait (37%), painful hands or feet (29%), and severe fatigue (13%). Questionnaires identified a wide range of behavioural problems. Most Patients showed good recovery of neurological deficits after GBS, but many have persisting long-term residual complaints and symptoms that may lead to psychosocial problems interfering with participation in daily life.

Quality of Life in Children with Asthma in Bangladesh.

Asthma is a public health problem that adversely affects different aspects of quality of life. Childhood asthma is common in Bangladesh affecting their lifestyle. The objective of the study was to assess health-related quality of life in children with bronchial asthma. A descriptive, cross-sectional study was carried out from January 2014 to December 2014 at the Outpatient Department of National Asthma Centre, Mohakhali, Dhaka among hundred sixty-two purposively selected children of both sexes with bronchial asthma aged from 7 to 17 years. Data were collected through interview with children or their parents using an interviewer-administered questionnaire based on Pediatric Asthma Quality of Life Questionnaire (PAQLQ). Data were analyzed by computer software SPSS version 16.0. The mean age was 12.5 years with a standard deviation (SD) of 2.9 years. Overwhelming majority 157(96.9%) of children were literate, while only 5(3.1%) children were illiterate. Eighty (49.4%) children were male, while 82(50.6%) female. As many as 148(91.4%) children were students, while 10(6.2%) children were engaged in some type of job and 4(2.5%) children had no occupation. Parents of 145(89.5%) children were currently married, while 10(6.2%) children had single parent and 7(4.3%) children's parents were divorced or separated. Quality of life in children with asthma decreases with age as the disease intensity increases with age. Female asthmatic children had lower overall score of Quality of life (p=0.017), as well as lower activity domain score (p<0.001). Emotional domain score was found lower in children with single parent (p=0.021) and low monthly family income (p<0.001). Furthermore, children with lower monthly family income and working children had lower Quality of life score in all domains.

Musculoskeletal disorder (MSD) among agricultural workers.

Farming is a large and main industry in Bangladesh. Large numbers of people are directly involved in farming and have very unique exposure compare to other sectors. Musculoskeletal problems among farmer population are not infrequent. This study was carried out among 200 farmers in one selected district. The study revealed that musculoskeletal problems were common among the farmers working in a traditional way. All the respondents were male. The age of all respondents lie between 20-60 years. Among them 22.5% farmers were illiterate, about 45.5% below Class V. About half (42%) of the respondents had reported pain in different parts of the body at least one or more times during working in land. And about two third (65.5%) of the farmers had history of joint pain and stiffness in last 12 month. Most of the farmers who suffered from musculoskeletal symptoms were 41-60 years. Specially who worked more then 20 years (82.6%) and average 6 hours per day (66.7%). The occurrence of musculoskeletal problems in various part of the body included Knee pain - 48.1%, Back pain (back ache) - 22.9%, Waist pain (low back ache) - 13.3%, Neck pain - 18.3% and shoulder pain - 10.7%. Length of work in year and daily average working hours were found significant association with musculoskeletal pain. It was found that musculoskeletal pain were more common among the farmers when they worked in squatting position (52%) and specially during weeding of plants (31%). Among them only 22% also engaged in other business. Most of the farmers complained dull aching pain (40.6%), only 2.3% noticed severe acute pain, but about 86% farmers' temporary stop their work for pain and 80% get relief after discontinue of work. About 75% respondents visited doctors for their pain which was statistically significant (p=0.001). It was found that the rates of musculoskeletal complaints are more among those individuals who worked relatively bad ergonomic condition, such as body position probably play an important role.

Iraqi parents' views of barriers to childhood immunization.

Deficiencies in knowledge about immunization among parents often leads to poor utake or errors in immunization dosage and timing. The aims of this study were to determine Iraqi parents' views of barriers to immunization and beliefs about ways to promote immunization. A questionnaire survey was carried out among 528 Iraqi parents with children who had incomplete immunization status. The main barriers to immunization agreed by the parents were lack of vaccine availability (51.5% of parents) and parents' lack of education (42.4%), while 88.4% of parents thought that lack of funding was not an important barrier. More than 60% of the parents suggested promoting childhood immunization via the media, and 77.5% thought that an increase in funding would not remove barriers to childhood immunization. Better vaccine availability in public health clinics and improving parents' literacy might enhance immunization uptake in Iraq.

Perceptions and treatment seeking behavior for dog bites in rural Bangladesh.

We conducted a study of the knowledge, attitudes and practices regarding dog bites among residents of a rural community in Bangladesh from September 2006 to February 2007 using face to face interviews with 1,973 adults from five villages. The mean age of the respondents was 34+/-16 years. Sixty-eight percent of subjects were female, 7.3% of respondents reported a history of dog bite in a family member; 10% had been bitten twice. Sixty-five percent of subjects were aware of rabies and 99.1% knew a dog bite was the cause of rabies. Seventy-one percent of subjects were aware of a rabies vaccine, 77.5% of respondents stated rabies can cause death. Ninty percent of dog bite victims received treatment by traditional healers, 25% were treated with a rabies vaccine and 2.1% of victims died. Greater awareness is needed in rural Bangladesh regarding prevention of rabies.

Melioidosis in an adult male.

Infection with Burkholderia pseudomallei has been described, albeit rarely, patients in Bangladesh. Infection usually follows percutaneous inoculation or inhalation of the causative bacterium, which is present in soil and surface water in the endemic region. A 35-year-young male farmer presented with prolonged fever and significant weight loss. Patient gradually deteriorated despite getting different antibiotics including intravenous ceftriaxone and metronidazole. Panels of investigations were done which revealed no diagnostic confirmation except uncontrolled diabetes and multiple abscesses in different organs. Melioidosis was suspected and serum samples were positive for Burkholderia pseudomallei antibody. The case illustrates the importance of non-specific nature of the clinical presentation and high index of suspicion of uncommon diseases like melioidosis where the disease has not been considered as an endemic.

Acute pancreatitis associated with acute viral hepatitis A (HAV) - a case report.

In this case report, a young woman had acute viral hepatitis (HAV) and acute pancreatitis together. She was admitted to our hospital with fever, jaundice and abdominal pain. Hepatic and pancreatic enzymes were elevated. Her serum alanine aminotransferase (ALT) level was high. An initial abdominal ultrasound was per-formed at hospital and revealed features of acute viral hepatitis. Spiral computed imaging revealed imaging features of an acute stage of pancreatitis and gallbladder wall thickness. HAV infection was diagnosed by the detection of immunoglobulin M (IgM) against HAV in the serum. She was closely monitored and treated conservatively. On 10th day of hospital admission she was discharge after an uneventful recovery. In the current literature HAV infections have rarely been reported as a cause of acute pancreatitis.

Phase II study of magnesium sulfate in acute organophosphate pesticide poisoning.

BACKGROUND: Acute organophosphorus (OP) poisoning is relatively common and a major cause of death from poisoning in developing countries. Magnesium has been shown to be of benefit in animal models. METHODS: We conducted a phase II study of bolus doses of (MgSO4) in 50 patients with acute organophosphate poisoning. Patients eligible for inclusion had ingested OP and had cholinergic symptoms consistent with moderate or severe poisoning. All patients received standard care of atropinization titrated to control muscarinic symptoms and pralidoxime. The trial was run in 4 sequential groups of patients. Participants in each group received a different total dose of MgSO4 (20%) administered as intermittent bolus doses infused over 10-15 min or placebo. There was one control patient for every 4 patients who received MgSO4. Group A (16 patients) received a total of 4 gm MgSO4 as a single bolus, group B (8 patients) received 8 gm (in two 4 gm doses q4H), group C (8 patients) received 12 gm (in three 4 gm doses q4H) group D (8 patients) received 16 gm (in four 4 gm doses q4H) and control (10 patients) received placebo). Patients were closely monitored for any adverse reaction like significant clinical neuromuscular disturbance and respiratory depression. RESULTS: No adverse reactions to magnesium were observed. The 24 hour urinary magnesium concentration were statistically different between 16 gm (234.74 ± 74.18 mg/dl) and control (118.06 ± 30.76 mg/dl) (p = 0.019), while it was much lower than the 80% of the intravenous magnesium load. Six patients died in control group compared to 3 in 4 gm, 2 in 8 gm and 1 in 12 gm group. There was no mortality in 16 gm group. CONCLUSION: Magnesium was well tolerated in this study. Larger studies are required to examine for efficacy.

Status of blood pressure among individuals consuming saline water.

Climate change is taking its toll in the form of saline water intrusion into the mainland of Bangladesh, which is one of the lowest-altitude countries in the world. The study was carried out with the objective to assess the blood pressure status associated with salinity in saline prone selected areas of Bagherhat and Tangail districts from March 2008 - June 2008 of rural Bangladesh. Two hundred and ninety subjects were selected purposively from both the districts. About 70% of the respondents were males and below forty years of age. More than two thirds of the respondents were illiterate; belong to 4-5 member family, with monthly family income of less than Tk. 4000 per month. Only one third of the respondents were smokers. More than two thirds of the respondents from salinity area had salinity level of 2-3%. Among them majority were drinking saline water for 6-10 years and 26% were drinking for more than ten years. About 20% of the non saline respondents' systolic blood pressure was 110-120 mm of Hg and 26% of saline area had systolic blood pressure >135-140 mm of Hg. Mean systolic BP among salinity area was more than that for non salinity area. About 19% of the non saline respondents' diastolic blood pressure was ≤ 85 mm of Hg. About one third had ≥ 90 mm of Hg, among them 31% were from saline area. Mean diastolic BP among salinity area was more than non salinity area. There was no history of heart disease, and less than 1% was diabetic among them. About two thirds had mean arterial pressure <70 mm of Hg, among them majority were from non saline area. About one third had >70 mm of Hg, among them majority were from saline area. The study concluded that systolic and diastolic blood pressures of saline group were significantly higher than that of the non saline group.

Re-emergence Nipah - a review.

There was an outbreak of new emergence viral encephalitis caused by Nipah virus among humans in some areas of Bangladesh during 2001 - till to date. The disease affected mainly the young, had increased suspicion to spread from bat to man through eating of the same fruits. The risk of human-to-human transmission is thought to be low though many of the affected individuals belonged to the same family. The disease presented mainly as acute encephalitis with usually a short incubation period of less than two weeks, with the main symptoms of fever, headache, and giddiness followed by coma. Distinctive clinical signs include areflexia, hypotonia, hypertension, tachycardia and segmental myoclonus. Serology was helpful in confirming the diagnosis. Magnetic resonance imaging (MRI) showed distinctive changes of multiple, discrete or confluent small high signal lesions, best seen with fluid-attenuated inversion recovery (FLAIR) sequences. Mortality was as high as 32-92% and death was probably due to severe brainstem involvement. Relapse encephalitis was seen in those who recovered from acute encephalitis, and late-onset encephalitis was seen in those with initial non-encephalitic or asymptomatic diseases. Both these manifested as focal encephalitis arising from recurrent infection.

Spectrum of skin lesions of post-kala-azar dermal leishmaniasis in kala-azar endemic areas of Bangladesh.

Post-kala-azar dermal leishmaniasis (PKDL) is a complication of visceral leishmaniasis (VL) and serves as a potential reservoir for Leishmania parasite. The study was aimed to evaluate the spectrum of skin lesions of PKDL in kala-azar endemic areas in Bangladesh. This cross sectional study was carried out to observe the characteristics of skin lesions among 250 PKDL cases. The suspected PKDL patients in highly endemic villages of Fulbaria Upazilla of Mymensingh district.were subjected to a dipstick test (rK39) for kala azar. The median time interval between diagnosing kala-azar and PKDL was 23 month (m-21, r- 0-60 months). The most common skin lesions were multiple symmetrical hypopigmented macules with irregular margins in 179(71.6%) cases followed by erythematous facial induration in 74(29.6%), papular in 33(13.2%), nodular in 28(11.2%) cases, combination of macules, papules, nodules and plaques in 88(35.2%) cases, annular in 7(2.8%) cases and Papillomatous mucosal growth in 2(0.8%) cases. Sites of involvement were mostly in face (92.4%), Trunk (84.8%), extremities (33.2%), oral mucosa and tongue (0.8%) and Genitalia (1.2%). Suspicion of PKDL on the basis of skin lesions will lead to early diagnosis and prompt treatment will impart an important role in prevention and eradication of Leishmaniasis in Bangladesh.

The impact of snake bite on household economy in Bangladesh.

The present study aims to assess the different types of costs for treatment of snake bite patients, to quantify household economic impact and to understand the coping mechanisms required to cover the costs for snake bite patients in Bangladesh. The patients admitted to four tertiary level hospitals in Bangladesh were interviewed using structured questionnaires including health-care-related expenditures and the way in which the expenditures were covered. Of the snakes which bit the patients, 54.2% were non-venomous, 45.8% were venomous and 42.2% of the patients were given polyvalent antivenom. The total expenditure related to snake bite varies from US$4 (US$1 = Taka 72) to US$2294 with a mean of US$124 and the mean income loss was US$93. Expenditure for venomous snake bite was US$231, which is about seven times higher than non-venomous snake bite (US$34). The treatment imposes a major economic burden on affected families, especially in venomous snake bite cases.

Puffer fish poisoning in Bangladesh: clinical and toxicological results from large outbreaks in 2008.

Poisoning after eating puffer fish containing highly lethal tetrodotoxin (TTX) is widespread in Asia. In 2008, naïve inland populations in Bangladesh were exposed to cheap puffer fish sold on markets. In three outbreaks, 141 patients with history of puffer fish consumption were hospitalized. Symptoms of poisoning included perioral paraesthesia, tingling over the entire body, nausea and vomiting, dizziness, headache, abdominal pain and muscular paralysis of the limbs. Seventeen patients (12%) died from rapidly developing respiratory arrest. Blood and urine samples from 38 patients were analyzed using a TTX-specific enzyme-linked immunoassay (ELISA). Medium to high TTX levels were detected (1.7-13.7 ng/ml) in the blood of 27 patients. TTX was below detection level (< 1.6 ng/ml) in 11 blood samples but the toxin was detected in urine. Ten patients had blood levels above 9 ng/ml and developed paralysis; seven of these died. The remaining patients recovered with supportive treatment. High concentrations of TTX and its analogues 4-epiTTX and 4,9-anhydroTTX were also found in cooked puffer fish by post-column liquid chromatography-fluorescence detection. To prevent future instances of puffer fish poisoning of this magnitude, measures should be implemented to increase awareness, to control markets and to establish toxicological testing. To improve the management of this and other poisoning in Bangladesh, facilities for life-saving assisted ventilation and related training of healthcare personnel are urgently needed at all levels of the health system.

Epidemiological manifestations of hepatitis C virus genotypes and its association with potential risk factors among Libyan patients.

BACKGROUND: The information on hepatitis C virus genotypes and subtypes among Libyan population and its association with various risk factors is not known. The objectives of this study were to determine the epidemiological manifestations of HCV genotypes among Libyan patients and their association with certain potential risk factors. METHODS: A total of 1240 of HCV infected patients registered at Tripoli Medical Centre were studied in five years period from January 2005 to October 2009. The information were reviewed and the data were collected. A sample from each patient (785 male; 455 female) was analysed for genotyping and sub-typing using specific genotyping assay. The information was correlated with the risk factors studied and the statistical data were analyzed using SPSS version 11.5. RESULTS: Off the total patients studied, four different genotypes were reported, including genotypes 1, 2, 3, and 4. Genotype4 was the commonest (35.7%), followed by genotype1 (32.6%). According to subtypes 28% were unclassified genotype 4, 14.6% were genotype 1b and some patients infected with more than one subtype (2.3% genotype 4c/d, 1% genotype 2a/c). Genotypes 1 was the commonest among males, while genotype 4 among females. According to the risk factors studied, Genotype1 and genotype 4 were found with most of the risk factors. Though they were particularly evident surgical intervention, dental procedures and blood transfusion while genotype 1 was only followed by genotype 3 mainly which mainly associated with certain risk groups such as intravenous drug abusers. CONCLUSION: Here in we report on a detailed description of HCV genotype among Libyans. The most common genotype was type 4 followed by genotype 1, other genotypes were also reported at a low rate. The distribution of such genotypes were also variable according to gender and age. The commonly prevalent genotypes found to be attributable to the medical -related transmission of HCV, such as blood, surgery and dental procedures when compared with other risk factors. This however, raises an alarming signal on the major steps to be taken to reduce such infection in Libya.

Central nervous system tuberculosis and adjuvant corticosteroid therapy.

Tuberculous involvement of central nervous system is one of the important health issues causing high mortality and morbidity. Uncertainty and doubt dominate all aspects of CNS tuberculosis. Diagnosis is mainly based on clinical features, cerebrospinal fluid changes, and imaging characteristics. Few studies have shown that corticosteroids improve the clinical outcome, although the precise mechanism of action remains tentative. All the cases were selected on strong clinical suspicion of CNS tuberculosis. They were graded according to tuberculous meningitis (TM) severity grades. In this connection, we studied 13 patients in one medicine unit over 12 month's period to see the effect of corticosteroid as part of the outcome. Nine patients (69.23%) were in grade II, three (23.08%) patients were in grade III, and one (7.69%) was in grade I. Seven patients (53.85%) had tuberculous meningitis and six (46.15%) had tuberculoma (CT or MRI). Out of 13 cases 3 patients (23%) died in the hospital and 10 patients (77%) improved, of whom 2 patients (20%) recovered completely and 8 patients (80%) had residual neurological deficit. Our study suggests that the early detection of CNS tuberculosis is the most important prognostic factor. Timely started anti-Koch's treatment with adjuvant corticosteroid therapy has a direct bearing on patient outcome.

A remarkable medical story: benefits of angiotensin-converting enzyme inhibitors in cardiac patients.

The development of angiotensin-converting enzyme inhibitors (ACE inhibitors) has been one of the most remarkable stories in the treatment of cardiovascular diseases. Angiotensin converting enzyme inhibitors have several acute and sustained hemodynamic effects that are beneficial in the presence of left ventricular (LV) dysfunction. They increase cardiac output and stroke volume and reduce systemic vascular resistance as well as pulmonary capillary wedge pressure. The hemodynamic benefits are associated with improvement in the signs and symptoms of congestive heart failure (CHF) as well as decreased mortality, regardless of the severity of CHF. In patients with asymptomatic LV dysfunction, therapy with ACE inhibitors prevented the development of CHF and reduced hospitalization and cardiovascular death. They also increase survival when administered early after an acute myocardial infarction (MI). Most recently, ACE inhibition was associated with improved clinical outcomes in a broad spectrum of high-risk patients with preserved LV function. The mechanism of ACE inhibitors benefits is multifactorial and includes prevention of progressive LV remodeling, prevention of sudden death and arrhythmogenicity and structural stability of the atherosclerotic process. Evidence suggests that ACE inhibitors are underutilized in patients with cardiovascular diseases. Efforts should be directed to prescribe ACE inhibitors to appropriate patients in target doses. It is reasonable to believe that ACE inhibitors have a class effect in the management of LV dysfunction with or without CHF and acute MI. Whether the same is true for ACE inhibitors in the prevention of ischemic events is not known yet.

Pregnancy-induced severe left ventricular systolic dysfunction in a patient with hypertrophic cardiomyopathy.

This paper reports the first case of hypertrophic cardiomyopathy (HCM) that developed postpartum congestive heart failure (CHF) and severe left ventricular (LV) systolic dysfunction. Review of the literature and clinical implications are discussed.

Digital pad transposition for replacement of the metacarpal or metatarsal pad in dogs.

A technique for digital pad transposition is described and illustrated. This technique has application for use in cases of metacarpal or metatarsal pad neoplasia or severe trauma. The transposed digital pad will provide a weight-bearing surface of heavy, keratinized epidermis in cases where the normal metacarpal or metatarsal footpad has been removed. The use of the technique in four clinical cases of footpad neoplasia also is reported.
